The Bishopry Militant knows this -- and so, when it needs a ship and crew to undertake a secret, sacred mission to a hidden land, Tephe is the captain to whom the task is given. Tephe knows from the start that his mission will be a test of his skill as a leader of men and as a devout follower of his god. It's what he doesn't know that matters: to what ends his faith and his ship will ultimately be put -- and that the tests he will face will come not only from his god and the Bishopry Militant, but from another, more malevolent source entirely....

    There, among an assortment of literary rarities, he discovers a manuscript in verse, an Ace Double Novel, and a scattering of very old cigarette butts. These commonplace objects serve as catalysts for an extraordinary - and unpredictable - adventure.Without warning, Blanzac finds himself traversing a "circle of discontinuity" that leads from the present day to the San Francisco of 1957. Caught up in that circle are an ancient Sumerian deity, a forgotten Beat-era poet named Sophie Greenwald, and an apocalyptic cult in search of the key to absolute nonexistence. With unobtrusive artistry, Powers weaves these elements into something strange and utterly compelling. The resulting story is at once a romance, a thriller, and the kind of intricately constructed time travel story that only the author of The Anubis Gates - that quintessential time travel classic - could have written. Ingenious, affecting, and endlessly inventive, Salvage and Demolition is a compact gem from the pen of a modern master, a man whose singular creations never fail to dazzle and delight.

The curator explains that the insect-like animals, no larger than Simon's fingernails, are not insects, but animals with a highly-evolved hive intelligence capable of staging wars between the different colors, and even religion - in the form of worship of their owner. The curator's warning to Simon about the regularity of their feeding, unfortunately, was not taken seriously...Contents:- The Way of Cross and Dragon (1979)- Bitterblooms (1977)- In the House of the Worm (1976)- Fast-Friend (1976)- The Stone City (1977)- Starlady (1976)- Sandkings (1979)Cover illustration by Michael Whelan

    The story was called "Nightfall", and many years later it has long been recognized as a classic, its author a legend. Now, the Gran Master of Science Fiction teams with Robert Silverberg, one of the field's top award-winning authors, to explore and expand an apocalyptic tale that is more spellbinding today than ever before -- Nightfall: The Novel.Imagine living on a planet with six suns that never experiences Darkness. Imagine never having seen the Stars. Then, one by one the suns start to set, gradually leading into Darkness for the first time ever. Kalgash is a world on the edge of chaos, torn between the madness of religious fanaticism and the unyielding rationalism of scientists. Lurking beneath it all is a collective, instinctual fear of the Darkness. For Kalgash knows only the perpetual light of day; to its inhabitants, a gathering twilight portends unspeakable horror. And only a handful of people on the planet are prepared to face the truth, their six suns are setting all at once for the first time in over two thousand years, signaling the end of civilization as it explodes in the awesome splendor of Nightfall.Encompassing the psychology of disaster, the tenacity of the human spirit, and, ultimately, the regenerative power of hope, Nightfall is a tale rich in character and suspense that only the unique collaboration of Isaac Asimov and Robert Silverberg could create.

    Smart, dedicated, gorgeous, and, thanks to her last movie before she hung up on Hollywood, rich, she's a pleasure to oblige when she says Rob has to witness this channeler Ariaura's act--on her, not the Eye's, nickel--despite channelers being so last year. It's quite a show, all right, for in the midst of Ariaura's particular ancient wise guy's basso spiel, a gravelly baritone interrupts (both voices emanate from the channeler's female mouth) to berate the audience as "yaps" and the act as "claptrap." Why is Ariaura undermining herself? Or is she? After all, she angrily accuses Rob and Kildy of scheming to destroy her. Could the baritone belong to a genuine channeled spirit? Willis, one of sf's most spirited writers, rounds on the New Age; pays tribute to a great, skeptical journalist; and affectionately parodies pulp fiction at its best in this irresistible entertainment.
